TPS61287 Evaluation Module
Description
The TPS61287EVM helps to evaluate the behavior
and performance of the TPS61287 at different input
voltages, output voltages, and load conditions. This
EVM is designed for 3.3V to 4.2V input voltage and
18V output voltage applications. This EVM has test
points of TP1 and TP2 for input voltage measurement,
TP3 and TP6 for output voltage measurement, TP7
for SW measurement, TP4 and TP5 for loop test,
respectively.
